"I was just very disappointed to let the team down."
Having not played any reserve-team football before his return to first-team action at the Madejski Stadium, it is unlikely Vaz Te will be thrown into the starting XI against Norwich City on New Year's Day. However, the Portuguese said he is desperate to contribute if required.
"I'm not sure I am ready to start yet. I have only trained the past week and I didn't play any games before. I played for 20 minutes at Reading and it was quite hard, so I'm just going to keep training to get my fitness as quick as possible.
"I will do my best if the gaffer decides to put me on. Personally, I don't think I'm ready to start a game but if that's the gaffer's choice I will always do my best, like I said."
Whether he features or not against the Canaries, Vaz Te believes West Ham can take heart from their second-half showing at Reading going into their New Year's Day fixture.
"We started out sloppy but the second half was much better. As the game went on, Reading got really tired and they opened up a bit more and we got opportunities - we just failed to score.
"They could have gone in and we would be celebrating, but they didn't and we're left disappointed."
